:50 alZ whom ifimay concern:

Be it known that I, LE GRAND SKINNER, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylva nia, haveinvented certain new and useful Improvements in Ore- Separators andC011Cll-' trators; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the ac companying drawings, and to theletters of reference marked thereon, forming part of this specification.

My invention relates to improvements in the mechanism and constructionof ore separators and concentrators, and particularly to that classknown as dry separators and concentrators. I

The objects of my invention are, first, the construction of the frame ofan ore-concentrating machine in two parts, the lower of which is madefixed and stationary, and the upper part journaled thereon upon a commonaxis with the driving-shaft of the machine, so as to permit the cantingof the upper part thereof laterally without interfering with theoperation of the driving mechanism of the machine; second, theconstruction of the frame of an ore-concentrating machine in two parts,the lower of-whichis fixed and stationary and supports thedriving-shaft, the upper part being movable and constructed in part ofafluidtight case inclosing portions of the operative mechanism of saidmachine, thereby protecting the same from the action of dust and grit;third, the construction of the parts of the frame and mechanism of anore-concentrating machine in sections, and connecting the same togetherby means of bolts, so that the machine can easily be taken apart andpacked in convenient packages for transportation.

I attain these objects by means of the mechanism illustrated in theaccompanying drawings, which form part of this specification, in which-Figure 1 is an elevation in perspective of my improved machine. Fig. 2is a vertical section of my machine on the line y in Fig. 3. Fig. 3shows in elevation one end of my machine, part in section, on line 2,Fig. 2. Fig.

.4 is a horizontal section of my machine on the line 90 :10 in Fig. 3.Fig. 5 shows in elevation one leg of the fixed frame of my machine, andalso in section the bearings of the driving-shaft mounted therein. Fig.6 shows in elevation one of the other legs of my machine. Fig. 7 shows ahorizontal view of one of the sections of the fixed frame of my machine.

Similar letters refer to similar parts of my machine through the severalviews.

The frame-work of my machine is composed of two portions, a lowerportion, which is fixed audstationary, and an .upper portion, whichrests upon the lower and is movable and ad justable. The lower or fiXGdportion of the frame is constructed in sections consisting of theinverted bracket-shaped legs A A, (one of which is shown in Fig. 6,) theleg 13, (shown in Fig. 5,) and the upper and lower frames, 0 and D, (oneof which, D, is shown in Fig. 7.)

In constructing the stationary frame of my machine, I bolt the upperends of the legs A A to the corners of the section D of the framediagonally opposite the opening in the side of D by means of bolts,which pass through suit able flanges, T, on the upper ends of the legs AA, and also through holes in flanges T on the corners of D, asillustrated in Figs. 1 and 4. The upper end of the leg Bis constructedof suitable width to fit the opening in D, and

is secured therein by a bolt or bolts passing through it and throughflanges on each side of the opening in D, as illustrated in Figs. land4'. The section 0 of the frame is of like shape and construction as thesection D, and the inner lower angles of the legs AA are provided withsuitable flanges, U, by means whereof they are secured to flanges U, onthe corners of G, diagonally opposite to the opening in the sidethereof,by bolts passing through said flanges U and through holes in the flangesU on the corners of the section 0. The leg B is secured to C by havingthe inner lower angle of the leg B fitted into the opening in the sideof C, and secured therein by bolts passing through flanges on C andthrough the leg B, the leg B thus fitting the opening in the sides ofthe sections D and O and securing the ends thereof together, asillustrated in Fig. 1. The driving-shaft F of the machine is journaledin the leg B (the same being shown in Figs. 1,

2, and 4,) and is provided with pulleys F, by means whereof the power tooperate the machine is communicated.

Within the sections and D (one of which is shown in Fig. 7) of the fixedframe of my machine I place the lower portion of the up per or movableframe of my machine. This I construct as a fluid-tight case, E. The caseE is journaled around the axis of the drivingshaft F and upon a commoncenter therewith, and is secured in place by a bolt, 1), passing throughone side thereof and through aslotted hole, I), therefor in the leg B ofthe fixed frame. It is also supported by the adj ustingscrews' G G, &c.,which pass through the parts 0 and D of the fixed frame, and as afurther support therefor its lower end rests on theinner edge of theportion 0 of the fixed frame,

as hereinafter described. The adjustingscrews G G, 850., pass throughthe opposite sides of the portions 0 and D ot'the fixed frame and pressagainst the edges of the case E, and serve to laterally adjust the caseE and that portion of the machine resting thereon for varying thehorizontal plane of the ore-bed Q, hereinafter referred to. To admit ofsuch lateral adjustment of the case E, the bolt 1) is provided with aslotted hole, b, in the leg B of the fixed frame. The bottom of the caseE is also made in the form of an arc of a circle having its axis on acommon center with the driving-shaft F, and at the point e the lower endof the case E rests on the inner edge of the frame 0 at a. By means ofthis construction and arrangement of the parts described of my machine,the caseE and the parts resting thereon, hereinafter described, can becanted or laterally inclined, as may be desired, without interferingwith the tension of the driving belt upon the pulley F.

Within the case E is placed the crank-disk h, which is .mounted upon theend of the shaft F, which extends through the side of and into the caseE, also the connecting-rod f, which connects the crank-pin with thecross-head which works in the guides H H, and the piston-rod I, whichextends out of the top of the case E through a stuffing-box, J, andforms the connection between the said cross head and the piston-valve.operating in the cylinder 0. The guides H H are inserted into the case Ethrough openings HH. These guides are provided with flanges which coverthe openings H H, and are secured in place by bolts through the sides ofthe case E and the flanges on the guides HH. Suitable packing is usedbetween the flanges on the guides H H and the case E, and by varying thethickness of this packing the guides H H can easily be adjusted from theoutside of the case E. 'l'hus that portion of the mechanism of mymachine consisting of the crank-disk h, connecting-rod f, guides H H,and part of the piston-rod I are inclosed in the case E, which protectsthese working parts from the action of the dirt,

sand, or grit of any kind. This case E may, if desirable, be filled withoil and water or with any suitable lubricating-fluid through oil-cups LL, which communicate with the inside of the case E at or above theguides H H.. The case E is also provided with hand-holes M and N N,which are closed by suitable covers secured in the ordinary way, thesecovers being adapted to be removed to adjust or repair any portion ofthe mechanism contained in the case E.

Near the top of the case E, and as a part cylinder-frame O rests, and towhich said frame is firmly bolted, as shown in Fig. 2. Thiscylinder-frame O is provided with a piston-valve, K, which is connectedwith the upper end of the piston-rod I, and is thereby operated. Thelower end of the hopper-frame P is constructed so as to rest'upon theupper end of the cyl- Tinder-frame O, andis secured thereto by bolts,

as shown in Fig. 2.

Uponthe top of the hopper-frame P is placed an ore-bed, Q, of ordinaryconstruction,which is held in place by the orebed frame R It, 850. Theore-bed frame R R, &c., is secured to the top of P by means of thehinged clamp S S, 850., as shown in Figs. 1, 2, and 3.

All of the parts, being constructed and arranged as shown and described,can readily be detached from each other byremoving the bolts securingthem in place, when desired, for transportation or other purpose.

scribed, as there is nothing novel in its construction; also, means forfeeding ore to the ore-bed, being well known and not forming any part ofmy invention, are not described.

In operating my machine, power is applied to the driving-shaft F,which,by means of the mechanism inclosed in the case, actuates thepiston-valve K, thereby pumping air upward against the under side of theore-bed Q in rapidly intermittent blasts, thereby producing a rapidvibration of the ore-bed Q, so that when arranged in position, as shownin Figs. 1 and 3, with the ore-bed discharge Q slightly lower than theopposite end of 'the ore-bed Q, and ore mixed with sand. and otherimpurities is fed upon the ore-bed at Q, the blasts of air from thepiston-valve K, and the vibrations of the ore-bed Q caused thereby,separate the lighter from the heavier particles. The ore, sinking downupon the bed, is. retained by cleats V thereon for that purpose, whilethe sand and lighter materials are discharged, by the operations of theair-blasts and the vibrations of the ore-bed, off of the ore-bed at Q;and when the ore-bed becomes charged with ore retained by the cleatsVthereon, it is removed from its frame and cleaned and replaced, when itcan be operated as before.

I am aware that machines of this class have been heretoforepatentedviz., Patents No.

212,330, to Edward IV. Stephens, granted thereof, is constructed aflange upon which the The construction of the ore-bed Qis not de- IIOFebruary 13, 1879, and No. 236,730, granted 1 July 18, l88l-showmechanism producing intermittent air-blasts upon the under side of anore-bed; and other parties have constructed ore concentrators in whichthe horizontal plane of the ore-bed can be varied; therefore I do notclaim the manner of operating the ore-bed by intermittent blasts of air;neither do I claim, broadly, the means for changing the horizontal planeof the ore-bed.

Having thus described my improvement, it is manifest to those skilled inthe art to which this invention appertains that many parts can bechanged and modified both in construction and arrangement. Ido not,therefore, desire to confine myself to the exact construction andarrangement of parts shown and described, as many variations willreadily suggest them-. selves to mechanics and others skilled in theart, which would operate well without depart ing from the spirit of myinvention.

WVhat I claim as new, and desire to secure by Letters Patent of theUnited States, is

1. In an ore-concentrating machine, a stationary base-frame and adriving-shaft journaled therein, in combination with a movable frame,and means for supporting and adjusting said frame on and around a commoncenter with the axis of the driving-shaft, substantially as set forth.

2. In an ore-concentrating machine, a stationary baseframe, incombination with an adjustable frame mounted thereon, the lower sectionof said adjustable frame being a fluidtight case, substantially as setforth.

3. In an ore-concentrating machine, a sta tionary base-frame constructedof the legs A A B and frames 0 D, the driving-shaft F, and theadjustingscrews G G G G, in combination with an adjustable framecomprising the fluidtight case E, the cylinder-frame O, the hopper-frameP, and ore-bed frame It It, all con structed and operating substantiallyas set forth.

4. In an ore-concentrating machine, and being a portion of the framethereof, the fluidtight case E, provided with openings H H, incombination with the guides H H, extending through said openings andadjustably attached to said case E, substantially asset forth.
